AI Technical Summary

Benefits of technology

The present invention is an image processing apparatus that can acquire an image, divide it into multiple parts, and extract similar image data from each part. It can also determine which parts of the image have a relationship to each other based on the extracted data and information about the image. This invention allows for more efficient storage and processing of images.

Problems solved by technology

Therefore, with the method discussed in Japanese Patent Application Laid-Open No. 2013-117860, detection accuracy of objects in regions other than a main region in the input image is low.

Embodiment Construction

[0026]An image processing apparatus according to an exemplary embodiment of the present invention extracts a plurality of partial regions from an acquired image, and acquires similar region(s) similar to the respective partial regions from an image database. The image database also stores information about a relationship between images. The image processing apparatus checks a relationship between the acquired similar regions based on the information, and determines that a common object is contained in partial regions similar to the respective similar regions that are highly related to each other or have an identical relationship. Then, the image processing apparatus combines the above-described partial regions, determines that combined region as a “target region (region of interest (ROI))”, and estimates a category of the object for each target region. In the present exemplary embodiment, “information about a relationship between images” corresponds to information in which image reg...

Abstract

An image processing apparatus, an image processing method, and a recording medium realize identification of an object region and a region category with high precision, estimate a relationship between partial regions in an acquired image by using a database about relationships between the images, and determine a target region in the acquired image based on the relationship.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to an image processing apparatus, an image processing method, and a recording medium for detecting an object in an input image and diving the input image into regions for each object.[0003]2. Description of the Related Art[0004]Conventionally, to execute post-processing such as image scene recognition or image quality correction according to an object, processing for detecting an object and dividing an image into regions for each object has been known. According to a method discussed in Japanese Patent Application Laid-Open No. 2013-117860, an input image is divided into a plurality of partial regions, and a similar image is inquired to a database for each of the partial regions, so that the input image is divided into regions by using the acquired similar image.[0005]However, according to the method described in Japanese Patent Application Laid-Open No. 2013-117860, components of a main re...
